3 steps to troubleshoot your internet connection
Struggling to get a signal or stay connected? Here are some tips to easily improve your connection:
- Adjust Roaming: Depending on your eSIM, you may need to enable or disable data roaming. Consult your eSIM instructions to determine the ideal configuration.
- Update your APN: Some eSIMs require an Access Point Name (APN) to be entered. Check the provided instructions and, if necessary, follow them to correctly modify your settings.
- Check your signal level: Make sure you have enough bars for 3G or 4G/LTE. If you are in an area with good coverage and still nothing works, try a complete restart of your phone. Turn it off, wait 30 seconds, then turn it back on to attempt a new connection.
How to make a call on a Dual SIM iPhone
With the Dual SIM feature of smartphones, you can simultaneously use an eSIM and a physical SIM card. This setup allows you, for example, to use the eSIM’s mobile data to access the internet, while retaining the physical SIM card for making and receiving calls.
To easily switch between your two lines on an iPhone with iOS 12.1 (or later), ensure you meet the following conditions:
- Own an iPhone XS, iPhone XS Max, iPhone XR, or a newer model.
- Have an unlocked phone or have plans from the same carrier.

How to proceed?
- Open Settings > Cellular Data (or Mobile Data) and choose the line you want to set as default for calls and messages not in your directory.
- Each time you wish to switch between your lines, go back to Settings > Cellular Data/Mobile Data and activate the desired line by selecting Turn On This Line.
This way, you can switch between your different lines at will, with ease, and fully enjoy the benefits of Dual SIM on your iPhone.
How to disable or delete an eSIM
The ability to save multiple eSIMs on your smartphone (even after their validity has expired) allows you to easily switch from one network to another. Nevertheless, if you wish to remove an eSIM or put it to sleep, you can easily do so from your phone’s settings.
Delete an eSIM
- Open your device’s Settings.
- Go to the Cellular or Mobile section.

Temporarily disable an eSIM
- Open your device’s Settings.
- Go to the Cellular or Mobile section.
- Select the desired eSIM line.
- You will see an option to enable or disable it: switch it to Off. You can then reactivate it later, whenever you need it again.
You are now ready to fully enjoy your eSIM experience!
